Calculate your carbon footprint

The Carbon Accounting tool in supplier+s makes carbon accounting it easier than ever. We know carbon accounting can be tedious and time consuming, so our module streamlines the process — straightforward, simple, and fast. Due to the simplicity of the tool, there are some limitations in the depth and detail of the information provided. Nevertheless, the most important aspects of your carbon accounting are covered.
 

According to the GHG protocol, Scope 1 emissions are direct greenhouse gas (GHG) emissions that occur from sources that are controlled or owned by your organization (e.g., emissions associated with fuel combustion in boilers, furnaces, vehicles).

According to the GHG protocol, Scope 2 emissions are indirect emissions from the production of energy your company purchases and uses (e.g., emissions from electricity generation for your buildings).

According to the GHG protocol, Scope 3 emissions encompass greenhouse gas (GHG) emissions that occur in your company’s value chain. Upstream emissions are those generated by suppliers during the extraction, production, and transportation of raw materials or components used in your organization’s products or services.

Yes, the Carbon Accounting module is free of charge; you can use it to calculate scope 1, scope 2, and scope 3 upstream emissions at no cost.

For deeper insights, an optional paid upgrade allows you to invite your suppliers to join you on your decarbonization journey on the supplier+s platform. This feature helpss you collect primary data directly from your suppliers, improving the precision of your carbon accounting and enabling you to track your emission reductions over time. 

A time-limited trial to invite your own suppliers is available to registered companies that have accepted at least one invitation from a client with a paid supplier+s license. See the Supply Chain Mangement section for details.

After the trial, inviting and managing your suppliers requires a paid license. Pricing depends on the number of suppliers you wish to invite. Contact us at sales@supplier-s.io for more information.

Carbon accounting requires joining activity data (from your organization) with (usually externally provided) emission factors. Those emission factors either come from industry statistics, or are provided by your suppliers.

We use the following sources for emission factors for the Carbon Accounting module:

• Emission factors for fuels (Scope 1) and district heat (part of scope 2) are taken from UK Government, Department for Energy Security and Net Zero, "Greenhouse gas reporting: conversion factors"

• Emission factors for electricity (part of Scope 2) are taken from the energy think tank Ember

• Scope 3 emission factors are sourced from item+s, a proprietary database developed by ctrl+s GmbH — operator of the supplier+s platform

• By inviting your suppliers to join the supplier+s platform, you can collect primary supplier data that is used to refine (or calculate) the emission factors used for your organization's carbon accounting.

The combination of activity data and emission factors follows two methodologies described and accepted by the GHG Protocol:

• For energy and energy carriers (Scope 1+2), we use your input of physical activities (given in units like kWh or liters) and combine it with the corresponding emission factors. This method is referred to as the "activity-based approach".

• For Scope 3 upstream, we use your input of monetary activities (given in USD) instead. This methodology is referred to as the "spend-based approach".

The carbon accounting provided by supplier+s is based on methods, procedures and external datasets that are in line with common reporting standards like the GHG Protocol and accepted by initiatives like the CDP or Science Based Targets (SBTi).

Please note that we apply some simplifications for the calculation of Scope 3 upstream emissions to ensure it is easy and straightforward to use without additional consulting support.

Please also note that we cannot guarantee a complete and correct application of the tool, as the calculation results also depend on the accuracy of the data you provide.

We value your privacy and keep the input of sensitive data to an absolute minimum. Unlike the self-assessment data, the data you enter on energy consumption and your procurement details will always remain private and will never be shared with any of your clients.

You may use the 'Copy results to self-assessment' function on the results page to share certain data from the Carbon Accounting module with your clients. If you choose this option, the aggregated results data will be transferred to the Organization Overview in the self-assessment (Namely the Scope 1, Scope 2, Scope 3 upstream emissions, and revenue). 

Please note that you have the option to use the Carbon Accounting Module as a starting point for your Supply Chain Management and invite your suppliers to participate in supplier+s to gain more insight into their carbon performance. If you choose to do so, this will impact the data we process and share with your clients (see information in the Supply Chain Management chapter).

Sharing of data between you and any client will always require your explicit consent (see section "Will my sensitive data be shared with the client(s) that invited me to supplier+s?" above for more information about what data you can choose to share). 

The supplier+s platform is operated by ctrl+s GmbH in compliance with applicable data protection requirements, particularly the European General Data Protection Regulation (GDPR).

We take data security extremely seriously. Our servers are located in the European Union, mostly in Germany. Data is end-to-end encrypted, and your data is segregated from other accounts in an independent database. We have implemented several security measures to ensure the safety of your data. Our data centers and IT infrastructure are certified with ISO27001, SOC 2 Type II, and SOC 1 Type II.
